Abstract Background The pathophysiology of isolated coronary artery ectasia (CAE) with the slow flow (CSF) phenomenon is still unclear. purpose this study was to investigate risk factors for CAE complicated CSF. Methods A total 126 patients were selected retrospectively. grouped into no CSF (NCSF) group (n = 55) and 71) according corrected thrombolysis in myocardial infarction (TIMI) frame coun...

OBJECTIVES Although drug eluting stents (DES) have documented convenience in bifurcation lesions, possible unfavorable effects on small side branch ostium (SBO) remain a question. We aimed to explore the effects of DES on small jailed SBs (1.5-2.25 mm) which originated from the lesion on the main vessel and were not treated with either stenting or balloon dilatation. METHODS Angiographic data...

Background: Angiographic flow measurements do not define perfusion accurately at a microvascular level, so other techniques which assess flow at a tissue level are to be preferred. Objectives: To compare intravenous myocardial contrast echocardiography (MCE) with other methods of assessing microvascular reperfusion for their ability to predict left ventricular function at one month after acute ...

INTRODUCTION The role of intracoronary (IC) eptifibatide in primary percutaneous coronary intervention (PPCI) for ST segment elevation myocardial infarction (STEMI) and whether time of patient presentation affects this role are unclear. We sought to evaluate the benefit of IC eptifibatide use during primary PCI in early STEMI presenters compared to late STEMI presenters. METHODS We included 7...

OBJECTIVE To explore hsCRP and ET-1 expressions in patients with no-reflow phenomenon after percutaneous coronary intervention (PCI). METHODS A total of 136 patients with single coronary artery disease receiving PCI were divided into a reflow group and a no-reflow group to compare the level use of ET-1 alone with combined level of ET-1 and hs-CRP in PCI regarding sensitivity, specificity, pos...

OBJECTIVES We sought to determine the prognostic value of mean platelet volume (MPV) for angiographic reperfusion and six-month mortality in patients with acute ST-segment elevation myocardial infarction (STEMI) treated with primary percutaneous coronary intervention (PCI). BACKGROUND Mean platelet volume is predictive of unfavorable outcome among survivors of STEMI when measured after the in...

Abstract Funding Acknowledgements Type of funding sources: None. Background There is emerging evidence showing improvement in clinical outcomes with optical coherence tomography (OCT) and intravascular ultrasound (IVUS)-guided elective percutaneous coronary intervention (PCI). Yet data supporting their use emergency setting are still conflicting. Purpose We aim to compare the immediate angiogra...

AIM Myocardial contrast echocardiography (MCE) is effective in predicting myocardial viability and functional recovery on a segmental level in patients with acute myocardial infarction (AMI). In this study, we investigated whether insufficient myocardial reperfusion plays an important role in left ventricular (LV) remodeling and functional recovery in patients with thrombolysis in myocardial in...

Abstract Background/Introduction Direct stenting has been proposed to reduce vessel wall damage and distal embolization in patients with ST-segment elevation myocardial infarction (STEMI) undergoing primary percutaneous coronary intervention (PCI). However, studies comparing direct after predilatation have shown mixed results so far. Patients presenting high thrombus burden the culprit lesion r...

Introduction: Microvascular and endothelial disorders play a significant role in the pathophysiology of coronary slow flow phenomenon (CSFP). However, according to previous studies, etiology CSFP is not completely understood. As CD40 dipeptidyl peptidase-4 (DPP-4) are reported an important atherosclerosis process as well microvascular dysfunction, this study evaluated these two biomarkers CSFP....
